PDW90 field units transmit analog, digital, and Modbus® inputs from any location in the field    to the PDW90 base station. Just set the network ID and Modbus address and put the field unit    wherever there is a 24 VDC power and a process signal. Once it has been connected to the base    station, it will transmit all signal connections wirelessly.
